I have installed Windows 10 on Bootcamp on a Late 2012 iMac and have OS X on the other side but keep having problems going back into OS X and Windows 10 when rebooting the machine. Yes I know its still a beta version but any idea on any software that I can run to allow me to boot into Windows 10 then back into OS X from Windows 10 (Think I can already do it from OS X)
